Title

Moldy Breads

Problem Scenario

What breads mold faster so that people know how long they can keep there breads.

Broad Question

What bread produces the most mold?

Specific Question

Will white bread get moldier then wheat or potato bread?

Hypothesis

Will white bread get more moldy then wheat bread or potato bread?

Graph of Hypothesis

Variables

General Plan

The general plan is to find out what kind of bread molds the fastest. I will put out three different
kinds of bread out in a room temperature room. then leave them to mold. I will check them a few
times a week and I will find the one that grows the most mold the fastest.

Potential Problems And Solutions

The bread might not mold in time.
All the breads may mold the same.

Safety Or Environmental Concerns

Make sure NO one eats the moldy bread.
Wash my hands every time i check the mold.
Throw it away the bread when it starts to mold.

Experimental Design

(add the correct headings from the experimental design page before beginning)

Controlled, manipulated experiment

What is your experimental unit?

The mold that grows on different types of bread.

Number Of Trials:

I will repeat this experiment once.

Number Of Subjects In Each trial:

I wont use different things. i will have all the breads in the same room and at the same temperature for the experiment.

Number of Observations:

8

When data will be collected

Data will be collected every Friday and Sunday until the experiment is done.

Where will data be collected?:

The data will be collected at my house or at school.

Resources and Budget Tablea

Item	Number needed	Where I will get this	Cost
white bread	1	the grocery store	1.50
potato bread	1	the grocery store	1.50
wheat bread	1	the grocery store	1.50
poster board	1	mr.Biche	5.00

Detailed Procedure

First i will need to get the potato, wheat and white bread.
Then i will put out one of each of the breads out to start to mold.
I will cheek it every once and a while. after two weeks or so i will
Take the observations and finish adding my data to finish my project.
Last i will finish my poster and be done!

Time Line

I will start my project on 2/1. my experiment will be done on 3/1.

Data Analysis

All Raw Data

\My bread didn't mold that is the only data I have.

Graphs

There was no mold and because of that I have no graph.

Photos

Results

My bread ended up not getting moldy even though it was out for five weeks.

Conclusion

My hypothesis was that white bread would mold faster then wheat and potato bread. I reject this hypothesis because in the end none of the breads molded.

Discussion

for my experiment I molded bread to see what bread would mold the fastest out of three different kinds of bread. In the end my experiment didnt work because the bread didnt mold. In the middle of my experiment my bread did get very stale. That was because it had started to dry out. I was really suprised that my bread didnt mold it just proves that there are some really bad chemicals put in are bread now a days. To improve my eperiment I could have molded my bread for a longer time if I had started it earlier. I could have also molded a whole loaf of bread instead of just a slice because we had a full loaf and it molded faster then my bread for the experiment. I could have also put a little bit of water so that it could mold faster. In the end I could have done alot of things to make this experiment better.

Benefit to Community and/or Science

my experiment can be used to help people find out what breads to get to save money because they dont mold as fast. the only problem with that is most breads that dont mold are filled with chemicals. lots of people could benefit from my project. people every where buy bread so this can help them figure out witch breads to buy if they want to save money. if they buy the bread that molds slower then they wont have to buy new bread every few days.

Background Research

bread is the most common food source of food. its because there is lots of nutrients in the ingredients for the mold to grow. it doesn't have a lot of wet ingredients so the mold grows better then bacteria or yeast because it doesn't need moister.

Abstract

For my experiment I wanted to know if white bread mold faster then wheat and potato bread. I put the three different kinds of bread out to mold. They were put in plastic bags and set on my counter. after five weeks all of the breads did not mold but it did got dry and hard. by the end of my experiment the bread had still not molded. that proves that they put some really bad stuff in breads because they are supposed to mold.
